Interleukin Genetics to Present Data Highlighting Link Between Inflammatory Gene Variations and Less Effective Weightloss

WALTHAM, Mass., January 22, 2009 /PRNewswire-FirstCall/ -- Interleukin Genetics, Inc. announced today that the company will present new research findings on the role genetics play in an individual's ability to lose weight and body fat while following a calorie-restricted diet, during tomorrow's Keystone Symposium titled, "Obesity: Novel Aspects of the Regulation of Body Weight." The Symposium, held January 20-25, 2009, is taking place at the Fairmont Banff Springs, Banff, Alberta, Canada.

Interleukin Genetics will present the study findings during poster session #3 taking place tomorrow, January 23, between 7:30 - 10:00 p.m. The poster, titled "Association of genes involved in chronic inflammation with weight management in response to the carbohydrate content of diet under calorie restriction," highlights new findings on the influence of genetic polymorphisms in the genes of interleukin-1 (IL-1) inflammatory pathway on dietary intervention induced weight and body fat loss.

"In this study, we investigated whether inflammatory gene variations were associated with response to weight-loss in overweight subjects," said Nazneen Aziz, Vice President of Research and Development at Interleukin Genetics. "We found that individuals with a specific genetic make-up were resistant to loss of body weight and body fat when they were placed on a calorie restriction diet, but individuals with the same genetic pattern were more likely to lose weight if their diet was not only calorie-restricted but also had a low glycemic content."

These results suggest that inflammatory gene variations could have important clinical utility in the design of optimal weight-loss programs in the overweight population.

The findings are the result of a study performed in collaboration with the Comprehensive Assessment of the Long-Term Effects of Restricting Intake of Energy (CALERIE) pilot research project, conducted at Jean Mayer USDA Human Nutrition Research Center on Aging at , Boston, MA. The one-year, randomized and well-controlled trial included high or low glycemic load calorie-restricted diets that were provided for the first six months, followed by extensive dietary guidance for the following six months. Body-weight, fat mass, resting metabolic rate (RMR) and insulin sensitivity were measured at baseline, 3, 6, 9 and 12 months. Compliance to the diet was monitored using the double-labeled water technique for the above five time-points of the study. Interleukin Genetics, Inc. performed the genetic analysis for this study.

According to the Centers for Disease Control and Prevention (CDC) more than 72 million U.S. adults and 16 percent of U.S. children are obese, while obesity-related health care costs have totaled over $100 billion. Obesity rates among all groups in society -- irrespective of age, sex, race, ethnicity, socioeconomic status, education level, or geographic region -- have increased markedly. Obesity is a significant global health problem and it has been associated with increased risk of several co-morbidities, such as Type 2 diabetes, cardiovascular disease and osteoarthritis. Inflammatory gene polymorphisms have been previously associated with body fat mass and implicated in inducing insulin resistance.
